Email sent from Sendgrid, can this be added direct to Google calendar as an 'attachment'?

Hi,

After successfully setting up adding events to google calendar via the Google API and a great tutorial by Lemondude. It has me wondering if it would be possible to add an email direct from Sendgrid to the ‘attachments’ section of Google calendar?

Thanks in advance!

Can anyone help with this one? appreciate its a little complex but just wondering if it’s possible…
